Title: Light communication device
Inventor: GADEI AIZENSUTAIN
IPC: H04B10/00
Filed: 1989-08-23
Abstract: PURPOSE: To reduce time for restoring a gain in an optical communication system of a specific optical data bit speed by making a carrier storing area adjacent to a gain area, so as to rapidly increase carrier density within the gain area. CONSTITUTION: Time for restoring a gain in an optical communication system of more than 1GHz bit rate of an optical data bit stream is reduced by making the carrier storing area 12 located adjacent to the gain area 10. Then the time in which the carrier moves from an area 12 to the area 10 is set to be shorter than the true life time of the area 10. This is attained by rapidly increasing the carrier density within the area 10, by generating the diffusion of the carriers from the area 12 to the area 10, by forming carrier density gradient between the areas 12 and 10 just after an optical signal has passed through the area 10. Thereby time of recovery of a gain is reduced and enables rapid recovery of the gain of an amplifier.

Title: Memory
Inventor: SENGOKU SHINJI
IPC: G11B21/08
Filed: 1982-12-09
Abstract: PURPOSE:To eliminate noises as well as the positioning mistake or error by integrating the position pulses of a memory medium which are obtained by reproducing and demodulating the information stored previously in the memory medium via a position reading head. CONSTITUTION:When a positioning instruction is sent to a magnetic disk memory from an electronic computer, a carriage is driven to count the output TP of an OR gate 17, i.e., the number of servo tracks. When the carriage reaches an instructed position, the position output +P or -P is controlled to hold the positin of OV. Then integrators 18 and 19 are provided to integrate outputs A and B of comparators 18 and 19, and therefore it is avoided that the output TP of the gate 17 is turned into an error signal by the noise N. Thus the noise N, if put on the output +P or -P and delivered to the outputs of comparators 15 and 16, is smoothed by integrators 18 and 19. As a result, no noise is produced to the output TP.

Abstract: PROBLEM TO BE SOLVED: To improve a throughput of an exposure step of removing a film to be processed on a sample wafer in its invalid region in order to lighten a dicing load and reduce dust, and also to prevent erroneous identification between valid and invalid chips. SOLUTION: A positive resist film is formed on a sample wafer W, and the wafer is subjected to a minimum number of shot exposures for transfer of a circuit pattern with use of a stepper only on a substantially valid region I of the wafer. An invalid region II is subjected to a food light exposure with use of a photo mask MF of food exposure having a 1:1 size relationship with the wafer under a condition that the valid region I is shielded. A throughput is improved by an amount corresponding to no shot light exposure of the invalid region II. Since no resist pattern is formed on the invalid region II, an underlying film to be processed is fully removed in the subsequent dry etching step so that no formation of a circuit pattern is made in a invalid chip CI.

Abstract: PURPOSE:To easily evaluate the characteristics of a photosensitive material by making the light emitting intensity of a laser diode, the rotational speed of a polygon mirror and the moving speed of a moving table variable. CONSTITUTION:A polygon mirror 10 is rotated at the speed controlled by a polygon mirror actuator driving signal (g) and, when a polygon mirror 11 is rotated, the laser beam (h) emitted from a laser diode 9 is reflected by the rotating polygon mirror 11 to transmit through an optical system 8 and swept while focusing the photosensitive material 7 an a moving table 6. When the moving table 6 is moved at this time, the exposed photosensitive material 7 is sent and can be exposed over the entire surface thereof. An arbitrary pattern can be drawn by controlling the flashing of the laser diode 9. As mentioned above, since the light emitting intensity of the laser diode 9, the rotational speed of the polygon mirror and the moving speed of the moving table can be changed, the photosensitive characteristics of the photosensitive material can be evaluated.
